This review is an overview of recent advances in diagnostics, therapies, and prevention strategies for cytomegalovirus (CMV), focusing on solid-organ transplant and hematopoietic stem cell transplant recipients.
A randomized trial of prophylaxis vs preemptive therapy in donor-seropositive, recipient-seronegative liver transplant recipients found significantly less CMV disease in the preemptive group. Maribavir has shown promise for the treatment of resistant/refractory CMV and for uncomplicated CMV DNAemia. A post hoc mortality analysis, as well as emerging reports of real-world and off-label use, have expanded the spectrum of clinical experience with letermovir. The first interventional trials using CMV cell-mediated immune assays have been published and showed promising results for delineating antiviral strategies. New data from additional interventional trials are expected soon.
The past 1-2 years have seen major developments in the area of CMV management in transplant recipients. Expanding diagnostic and therapeutic capabilities provide a foundation for optimizing strategies in the future, to reduce morbidity and mortality from CMV.
